Br ana, a citizen of the United States, and resident of Syracuse, in the county of Onondaga, in the'State of New York, have; i11

vented new and useful; Improvements Shade-Roller Attachment-s,- of which thefoh lowing, taken in connection with the accompanying drawings, is a full,clear,;and exact descri tion, v

This 'n'ventio the class of shade-rollerswhich are actuated. to automatically wind up the shade by-means of a spiral spring-surrounding a stationary spindle and conneetinglsaid spindle to the IThe object of.- this invention is to furnish to the trade a shadesrollerattachment which shall beicomposed; ofaniinimum number ofseparately formed. parts, of simple construction which areIveigvgconveniently and compactly assembled; and readily secured to-the roller equipped with the stationary spindle And ,to.that eiidtheinvention consists in the improved construction and combination of. the component parts of the shade-roller attachment hereinafter described andclaimed. In the accompanying drawings, Figure l is a face view of my improved means 'for supporting, the catch-plates; of the shade: roller; Fig. '2 isa longitudinal sectionon the I line Fig. 3 is an inner iacejview of the catch-plate supporting disk; and, Fig.

A represents the spring actuated. shade-roller which is formed hollow as shown at a-, and has arranged in it the spindle -b, which, by means of a suitable spring connecting it to'theroller; causes the said roller to wind up the shade in the usual manner. j

-edenotes the so 'called spear which is attached to the end of the spindle -b. and is formed with a hub fprovided with notches 'f .f and terminated in a flattened portion engagin the adjacent support ing bracket of there ler in the well known manner.

My present invention-consists in theimproved construction and combination of the component parts oftheroller-controlling de vices which are as follows, to wit:

-1- represents a disk which is formed from sheet metal and secured stationary directly on the end ofthe roller -A-as r Be it known that I, JAMES V. WASH? n' is designed to-be applied to.

hereinaiterdescribed and. is provided with. a central aperture 3 for receiving through it the flattened end portion g and the notchedpart of the hub --f of the spear The outer face of said disk is formed ,With aflat bed on which are seated-the slidable catch-plates -6+- each. of which is formed with a tooth 7y.which. is shaped to engage oneata time the notches -f in -'ro guide the. catch-plates. in-their movementsto. and fromthe spear and to enable said plates to more effectually .resist "the strain-received from the spear when inter? locked therewith, I formthe disk- 1 with elongatedguidesadjacent to the,. sid e edges of the catch-plates and with stops for limit-' ing the movement of said plates from their engagement with the spear Said guldes and stops consist offlanges -7-55 and 5 -5 which consist of marginal portions of the disk bent at right angles Iron) guide flanges 5-5 with-lips 5 projecting inwardly from said flanges as shown in Fig. 4.

" To cause the disk to obtain a firm and se-- cure grip on the roller so as toeffectually prevent said disk from turning and slipping circumferentially on the roller, I provide the edges of said disk with calks -99 projecting from the inner side-0f the disk, referably at .the en ds offthe flanges 5-5 and piercing the face of the roller, as shown inFig. 2' I form the said calks from'the marginahportions between the ends of the flanges --5 and -5" which intermediate marginal. portions I bend .at right angles from the plane of the disk and in opposite directions from the said flanges is shown in Fig. 5. It will be observed .that the disk -I with its flanges 5 and -5 and calks 99- is readily stamped. from a Patented Feb. 16, 1909.

thin sheet of'metal andis-simple and inexpensive to manufacturer 7 The ierced portion of the roller is reinforced y means of a ferrule 11 which firmly embraces said portion of the roller and extends beyond the same to grip the body of the roller as shown in Fig. 2.

- The outer end ofsaid ferrule'is extended and formedwith acap '-10- to shieldthe disk --'-1-=- and catch-platesj-6-.

veniently and quickly assembled.

W hat I claim as my invention is:

1. As an improved article of manufacture, the within described catch-plate supporting disk composed of sheet metal and having the guide-flanges formed oi marginal portions of the disk bent u) at right angles from the'plane thereof an constituting part of the boundary of the disk as set forth.

2. As an improved article of manufacture the catch-plate supporting disk having .the fiat supporting-bed consisting of the main portion of the disk, and the guide walls;

formed from the two opposite margins. of the disk turned up at right angles from the plane thereof and the edges of said margins bent toward each other, all struck up in one piece of sheet metal.

As an improved article of manufacture, the catch-plate supporting-disk, having the supportingbed consisting of the main portion of the disk, the guide-Walls formed from the two opposite margins of the disk turned up at right angles from the plane thereof, and attaching calks consisting of marginal portions of the disk projecting .from the disk in opposite directions from the aforesaid walls, all struck up in one piece of sheet metal.

4. As unimproved article of manufacture, the catch-plate supporting disk having the disk bent to project from the disk in the opposite directions from the aforesaid walls, all struck up in one piece of sheet metal as set forth.

5. As an improved article of manufacture,

the within described catch-plate supporting disk having parallel guide flanges and transverse stop flanges at the ends of the parallel flanges, all formed from integral marginal portions of the disk and bent to project from one side theieof and calks formed from intermediate marginal portions of the disk bent to project from the opposite side thereof.

6. As an improved article of manufacture, the Within described catch-plate supporting disk having parallel guide flanges, inwardly projecting lips on the edges of said flanges, and transverse stop flanges at the ends of said parallel flanges all formed from integral marginal portions of the disk and bent to project from one side thereof, and calks formed from intermediate marginal portions of the disk bent to project from the opposite side thereof.
